New Cable Modem Speed?? Is it possible?

Code: Select all
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 373360
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 46670
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 14934.4 kbps (1866.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 5973.76 kbps (746.72 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = OFF
Time to live left = 50 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
Did anyone got something like that from this?
THX
btw... I was able to download a 50Mb file in 55 sec at 913kb/sec
